UNITED STATES JAMES J. BARRETT, OF WHITE BLAINS, NEW YORK, ASSIGNOR TO BARRETT BLUE BLAZE BURNER 00., INC., A CORPORATION OF NEW YORK.

OIL-BURNING APPARATUS.

Application filed January 9, 1924. Serial No. 685,165.

To all whom it may concern:

Be it known that I, JAMES J. BARRETT, residing at White Plains, county of Westchester, and State of New York, have invented certain new and useful Improvements in an Oil-Burning Apparatus,- of which the following is a specification.

This invention relates to an improved oil burning apparatus, and one of the ob j ects of the invention is to provide a new and improved oil burner.

Another object of the invention is to provide a liquid fuel burner, wherein more complete combustion of the liquid fuel is had than in burners of this character as hitherto constructed.

7 Another object of the invention is to provide a liquid fuel burner, which will not become clogged up by the carbonization of the constituents of the liquid fuel, and which may therefore be, operated for long periods of time without care or attention, or the necessity of cleaning, to remove carbon deposits which in burners as hitherto constructed, interfere with their effective operation.

'A further object of the invention is to provide an oil burner construction wherein the air utilized in the combustion of liquid fuel will be heated before being discharged into the burner.

Other objects and aims of the invention, more or less specific than those above referred to, will be in part obvious, and in part pointed out, in the course of the following description of the elements, combinations, arrangements of parts and applications of principles, constituting the invention; and the .scope of protection contemplated will be indicated in the appended claims.

In the accompanying drawings, wherein I have illustrated a preferred form of em-- bodiment of my invention:

Figure l is a vertical sectional view taken through the fire-box of a heating apparatus,

, also showing my improved burner in vertical section. I v

Figure 2 is a bottom plan view of a bafile plate, employed in connection with my in- 0 vention.

Figure 8 is a vertical sectional view taken through a burner of a-v slightly modified construction.

4, the latter being preferably goblet shaped,

as shown, supported by a vertical standard 5, mounted for vertical adjustment in a base 6, which rests upon the floor of the fire-box. Adjustment of the standard 5 may be accomplished as by means of the set screw 7. The burner 4 is preferably formed of a cup-shaped member, into which the liquid fuel 8 is discharged by means of a feed pipe 9, which leads from a float valve construction, 10, into which leads a conduit 11 from a source of oil supply 12. Any approved form of a float valve construction, illustrated at 10, may be employed, the object being to maintain a constant predetermined level of the liquid fuel 8 in the burner 4.

Extending laterally into the burner 4 is a conduit 13, which conduit terminates in a downwardly extending funnel-shaped outlet end or nozzle 14, located centrally of the interior of the burner. Inasmuch as the conduit 13 within the burner is directly. above the burning liquid fuel, the air discharged thereto will be preheated before it passes through the outlet end or nozzle 14. The outlet end or'nozzle 14 discharges the preheated air downwardly into the central portion of the flame, the construction-being such that the preheated air is forced against the entire surface of the burning liquid fuel. Surrounding the outlet or nozzle 14 is a circular plate or baffle 15. The discharge opening of the nozzle 14 is located slightly abovethe normal level of the liquid fuel. The burner 4 is surmounted by a baflle plate 16, havin the legs 17, which rest upon acircular ange 18, formed exteriorly ofthe burner. This baffle plate 16 is located above the upper open end of the burner 4, providing the space 19, through which the flame from the burner passes into the fire-box. The air conduit 13 is connected by means of the conduit 20, with a source of air supply, such for'instance as synchronism, and the operative relation of said valves may be changed by adjusting their 0 erating handles in the slots 26 and 27 of t e rod 28.

Mounted upon the standard 5 is a cup 31 ada ted to hold a small quantity of liquid uel, which liquid fuel may be discharged into said cup through a nozzle 32, provided upon a branch conduit 33, leading from the fuel conduit 9, which branch conduit is controlled by means of the valve 34:.

Referrin now to the embodiment of my invention s own in Figure 3 of the drawings, the burner 4, which is formed similarly to that already described, has leading throu h the bottom wall thereof an air condult 35, the upper end 36 of which terminates slightly above the level of the liq-- The baffle plate 16' uid fuel in the burner. has a downwardly extending stem 37, the latter carrying a baflle plate 38, against which the air which is discharged through the tube 35 is projected.

Having thus described my invention, the operation thereof, which should be largely understood, is substantially as follows It will be understood that Figure 1 of the drawings shows schematically the burner and its associated parts comprising the system, ready for operation. The liquid fuel within the burner may be initially ignited by thrusting a torch through the aperture 19 between the baflle 16 and the upper end of the burner into the body of liquid fuel contained therein.

Prior to this operation, the liquid fuel contained in the cup 31 has been ignited in a similar manner, the operation of this fuel preheating the fuel within the burner, rendering it easier to ignite. \Vhen the fuel in the burnerhas been ignited, the

valves 22 and 23 are opened, whereby when the blower 21 is set, into operation, air is discharged downwardly through the nozzle 14, upon the burning fuel within the burner. The flames pass upwardly through the open upper end of the burner, outwardly, into the fire-box, through the aperture 19, be neath the bafile plate 16.

Referring again to Figure 1 of the drawings, I have shown a conduit 39 connected with the conduit 20. The conduit 39 will preferably-lead from a source of steam supthe baffle 38, the flames being discharged through the aperture 19, between the upper end of the burner and the baffle 16, as in the first described embodiment of my invention.

It will accordingly be seen that I have provided a construction well adapted to attain, among others, all the aims and objects above pointed out. It will be noted that the air entering the burner will be preheated before its discharge from the nozzle 1a against the surface of the flaming liquid fuel.

' It will also be noted that the burner can be cleaned automatically by closing the valve 23, thereby shutting off the supply of liquid fuel to the burner, whereby when the volume of liquid fuel gradually decreases in'theburner, all carbon deposits will be removed.

It will also be noted that the relative adjustment of the valves 22 and 23 provides for the discharge into the burner of the desired proportions of air or steam and the liquid fuel.

As many changes could be made in this construction without departing from the scope of the following claims, it is intended that all matter contained in the above description, or shown in the accompanying drawing, shall be interpreted as illustrative only and'not in a limiting sense.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is: i 1

1. A burner of the class described, eomv within said receptacle, said means for discharging said fluid, being partially located within said burner, so that the fluid will be preheated before it is discharged into the burner, and means for simultaneously controlling the flow of liquid fuel and fluid into said burner.

2. In an oil burner of the class described the combination of a receptacle having an opening upwardly therethrough, means for feeding a liquid fuel into the receptacle to a predetermined level, a bafiie supported by the receptacle at a location above the baffle with the bafile depending within the receptacle in spaced relation at its outer edges from the inner wall of the receptacle and so that a transversely unobstructed space is provided between the baffle and the liquid level, and means for discharging a blast of air into the receptacleinto the space between the bafile and the liquid level in the receptacle vwhereby the blast of air and the vaporized oil therewith must travel between the outer edge of the bafiie and the inner surface of the receptacle upwardly towards the opening in said receptacle.
